One of the materials used in the GiMialign AI 3D Kinetics Socks is combed cotton, which is crafted into a cushion-like texture. Combed cotton has a unique characteristic: it may shed some fibers initially, but it will not form pilling. In contrast, synthetic cotton fibers do not shed fibers but instead form pilling and clumps. This characteristic of combed cotton can easily be verified online. This means that the GiMialign AI 3D Kinetics Socks are made with authentic combed cotton!
